Re the Hammers for your piano:  I have used Renner hammers and I like
them _a lot_.  I am not able to hear your piano, though, so I can't
tell you via e-mail what you should use.

Try to find a local tech that has done hammer work.  There are Fords
& Chevys & Dodges, though, so weed through the opinions to get what is
best for your piano.
